Light, Flexible PVC Hard Suction Hose for Drafting

Accept no substitutes: Maxi-Flex is the original lightweight PVC suction-only hose. Simply built smarter, its special corrugated PVC exterior provides maximum flexibility and a smooth waterway for superior flow. Clear flexible PVC between the helix ribs allows full view of water, while distinctive black helix ribs deliver maximum UV protection. Lightweight and ultra-flexible, Maxi-Flex hose affords one person hookup operation with extruded aluminum re-attachable, bolt-on couplings. Designed for suction only—purpose-built for full vacuum; drafting any rural or municipal non-pressurized water source.
